Spectral Effects of Shock Darkening On Ordinary Chondrite and Howardite, Eucrite, And Diogenite Meteorites
Impacts are the most ubiquitous processes on planetary bodies in our solar system. During these impact events, shock waves can deposit enough energy to produce shock-induced darkening in the target […]
